TITLE: WordPress Cross-Site Scripting Vulnerabilities SECUNIA ADVISORY ID: SA19050 VERIFY ADVISORY: http://secunia.com/advisories/19050/ CRITICAL: Less critical IMPACT: Cross Site Scripting, Exposure of system information WHERE: >From remote SOFTWARE: Wordpress 0.x http://secunia.com/product/1659/ Wordpress 1.x http://secunia.com/product/3978/ WordPress 2.x http://secunia.com/product/6745/ DESCRIPTION: K4P0 has discovered two vulnerabilities in WordPress, which can be exploited by malicious people to conduct cross-site scripting attacks. Input passed to the "Name" and "Website" parameters in wp-comments-post.php isn't properly sanitised before being returned to the user. This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site. It is also possible to disclose the full path to certain scripts by accessing them directly, disclose the content of certain directories, and by administrators to inject arbitrary HTML and script code via the "comment" parameter. The vulnerabilities have been confirmed in version 2.0.1. Other versions may also be affected. SOLUTION: Edit the source code to ensure that input is properly sanitised.
